[Boost-users] Boost IPC shared queue

Hi, I am trying to build a shared queue between a reader and writer thread of my process. I am creating a managed shared memory segment, defining an allocator on top and using the same to initialize a shared queue. I have a question related to the edge case, considering there is a disparity in the speed of the reader and writer threads and the writer thread pumps in more data than the shared segment size, what is the expected behavior of the queue? Will it allocate a new memory segment or block the writer thread or throw an exception? Are there any links or references for the same? I had a look at the boost ipc documentation, but did not see any text explaining this scenario. Thanks and regards, Sid
